A new build CNCRP, Mach3, EthernetSS and PMDX126.
I am configuring my Z for setting tool height and realized I had previously installed a hard mechanical limit switch wired to the E-stop (trips both high and low). Yes I do have to manually move it off when it over travels but I hope this will eventually be rare with good code and working soft limits.
Why couldn't I just use a block of known height, connected to this circuit, and run the tool down till it E-stops and enter into Mach3 the height or the measured distance (which should be a constant after a few tries). The block could go on the table or the work piece and have a hard rubber section for some spring, the top soft metal. Once you pull the block the E-stop would be gone. I know I have plenty i/o with the SStepper but this still seems very easy... too easy? Am I over looking some conflict(s). Thanks Edward
